Ordering Landscape Layers on Component Landscape

I have a component landscape I have imported from World Machine, it is currently made up of a heightmap and 5 layers, one for coastline(sandy beach), a couple for grass, stone for mountains, and snow.

On engine import, the layers aren’t ordered correctly.

Ideally, I would like sand to be the lowest layer, followed by stone, then grass, then I want snow to cover everything?

Is there a way to change the order of layer colors? Currently, sand is the top layer followed by grass, the problem here is there is some grass overlap to make blending to sand look nicer, but with sand being top you can’t see blending. (I want sand under grass not over)

Do I need to reimport for this to take effect?
Initially(on import) the layer blend was ordered: sand followed by grass and rock.
Once I saw the incorrect order I swapped the layer blend order but that did nothing. Would reimporting landscape work?

Is there any other method to change order?
